HOT-WATER HEATER.

Speceation of Letters Patent.

Patented Feb. 4, 1908.

Application iiled March 5. 1907. Serial No. 360.693.

To all 'whom it may concern:

Be it known that we, JOEL A. and EDDIE IV. COPPRIDGE, citizens of the United States, and residents of Richmond, in the county of Henricoand State of Virginia, have invented an Improvement in Hot-Tater Heaters, of which the following is specification.

This invention is an improvement in hot water heaters, and consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed.

In the drawings, Figure 1 is a front view, and Fig. 2 is a vertical longitudinal section of a heater embodying my invention. Fig. 3 is a vertical cross section thereof. Fig. 4 is a horizontal section of the body below the baffle partitions. Fig. 5 is a cross section on about the line 5 5 of Fig. 2; and Fig. 6 is a top plan view of the heater.

The heater comprises a body A mounted on a suitable base B and having a lire pot O to which access may be had through a door D. The base B may preferably be cast and the outer casing A1 and the inner casing A2, the latter extending along both sides and the back of the body and being spaced away from the outer casing A1 forming a water space or chamber E extending around three sides of the body, and extended at E1 to form a water space above the lire pot O, any suitable means, such as stay bolts e shown, being provided for holding the parts A1 and A2 properly spaced apart. The base B affords an ash box below the grate B1, a suitable ash door B2 being provided, and along the inner side of the front F of the box A I provide below the door D a water back G which may be suitably connected with the water supply and with the water pipe system of the house to supply het water to the house being heated. A suitable outlet H is provided for the products of combustion, such outlet being located at the top of the iire box O, as best shown in Fig. 2, and preferably consisting of a pipe riveted in connection with the parts A1 and A2, as shown in Fig. 2.

Hthin the lire box and below the discharge outlet, I provide a series of baffle partitions I, I1, I2 and I3. These partitions are alike in construction, exce t as to proportions, as presently describec, and they project alternately from the opposite ends of the body over the vfire pot, and nearly to the opposite end of the body, affording contracted passages i between the free ends of the partitions and the adjacent walls of the body` The lower partition projects from the front wall of the body toward the rear wall, and the upper partition projects from the rear wall immediately below the discharge H toward the front wall of the body, and the intervening partitions alternate as best shown in Fig. 2. These partitions comprise a plurality of series of tubes l, 2, 3 and 4, extending from side to side of the body and communicating at their opposite ends with the water space E, being suitably connected with the inner casing plates A2, as shown in Fig. overlying their respective tubes 1, 2, 3 and 4, as shown in Figs. 2 and 3. The tubes of each series are preferably of uniform diameter, and the tubes of the several series decrease in diameter toward the top of the lire box. In other words, the tubes of each of the series are smaller than those of the next lower series, so that as thc heat passes upwardly around the several partitions, and decreases in intensity, the area of the water to be heated will also decrease, this being best illustrated in Figs. and 3 of the drawings.

For cleaning out the spaces between the several partitions, I provide atthe front of the body A, doors K arranged in two vertical series, adjacent to the opposite sides of the heater, so a scraper or other suitable implement may be inserted to the spaces above the partitions for cleaning out the soot and other material accumulating thereon. It will be noticed that the material may be scraped from the upper partition on to the next lower, thence to the next lower, thence to the lower partition, and thence into the fire pot.

Pipes L lead from the top of the hot water space .E to the radiators, and return pipes M from the radiators open into the space E at the bottom thereof. It will be noticed that these pipes L and M are arranged in series and correspond, and that when one or more of the feed pipes L are not in use, the corresponding pipe or pipes M may be plugged, thus equalizing the circulation in the use of the heater as is desirable.

wWe claim:

A hot water heater comprising a body and a lire pot therein, the body having a water space, or chamber extending around three sides thereof and havingl the other side of the body provided with a door above the fire 3, and plates J, J1, J2 and J3,

pot and the said sidebeing provided below l series being smaller than thosel of the next such door with a water back forming one side of the fire pot and connected with the main water space or chamber of the body, a series 5 of alternating baffle partitions extending within the body from side to side thereof and terminating alternately at points spaced away from the walls of the body7 said partitions comprising a series of tubes and plates 10 overlying the same, the tubes of the several lower series and the tubes of the several series connecting independently with the water space of the body, substantially as and for the purpose set forth.
